There is a missing piece of automation here still.
The robot can replicate recorded movements - brush angle, pressure, timing etc.
An photoshop filter can shift pixels around to make a photo look like an oil painting.
What nobody has come up with yet (and would likely be hard to develop, or at least costly) is a way to translate a photograph, or a photoshop filter into the set of movements required to render it in physical oil paint.
